System for assessing radiation treatment plan segmentations

摘要

Segmentations used to describe structures to be treated by radiotherapy are evaluated by converting the segmentations into volume models and examining volume elements that are extra or missing in the volume model of the second segmentation with respect to the volume model of the first segmentation. This characterization of volume elements may be displayed graphically to show differences in segmentations for training or evaluation purposes and may be quantified by a metric method tallying volume elements as optionally weighted by distance from volume elements shared by the segmentation.
